I Figure 5 is aplan viewer an edge strip of the invention'sh'owin'g representative 'modifications'which can be inclfidd therein. v 'Figure s 'is'aemss-sectionerthe edge strip shown in Figure 4 taken'alon'g the line 66. I This invention consists of providing a ski generally designated entire drawing as 2, which has "a weede n runner "seetion 4"an'd a plastic bottom e6ating6 with a plurality or end abutted' metal edge strips lo. The edge, strips 10 are positioned 'e'nd- 'toe hd "atthe bottom dgesofftheski 2 and formacute angledsharp bottom 'cnrne'rslz for substantially the entire length ofth'e" According to the invention thee'dge "strigs 10 "are os fioned'betwen the "wooden runner 4'a'nd the plastic bot: tom coating 6 *an'd'ror a major portion of "their width are inclined 'at an angle '14'o'f a proximatel 'ten degrees 't'o t'he bottom surface '15'of the ski 2. The outside edge portions 16 of the strips 10 are turned down along a longitudinal fold line 17 to make an angle 18 hi approximately 167 degrees with the side '24) of runner 4, as indicated in Figure 1. Edge stripslof formed and 'posi tiohd as indicated do not materially afie'ct the bond between the "Wood runner 4 and the plastic bottom coating 6 when the ski 2 is flexed longitudinally and they greatly reduce'skidding of the ski when it is in use. p

Also, according to the invention the individual edge strip sections 10 are provided with means to increase the bond between the wood runner 4 and the plastic coating Gin the vicinity of the sections 10. increased bond in this vicinity is desirable as most bonding failures between the plastic bottom coating 6and the other members of skis having metal edge strips occur in the vicinity of the edge strips. 7 v V 'Ihe' major-unit of the ski 2 shown in the drawings is' the wooden runner}. The composition and general form of such runners is well known and will not therefore be discussed here The bottom and lower side portions oi 'therunner '4 of this invention are believed to be unique and therefore will be described in detail. The bottom surface 22 of runner 4 is inclined upwardly {for a short distance at an angle of approximatelytten degrees'with thenon-inclined central bottom surface z j. The inclined surface 22 as shown in Figure 1, extends from the lower "corner of the runner and toward the center of the ski. An inclined-surface 22 is provided on both'si des'of the bottom of runner 4. The inclined surfaces 22 extend as shown in Figures 2 and 3' for substan-, tially the entire length of the ski 2. Inclined surfaces 22 are terminated at surfaces 26 which are also provided on both sides offlthe bottomlof runner .4 and which con:

The outside edge 27 of the bent down portion 16 of edge strip 10 therefore forms anacute angle with the bottom surface of'ski 2. with such construction, when ski Zskids while in use acute angled edge 12 will bite into the sliding surface and will be forced further into the sliding surface as skidding continues by inclined surface 27, thereby greatly.

restricting the skidding movement.

Edge strips 10 are also provided with countersunk holes 28 and screws 29 to facilitate the screw attachment -of strips 10 at the lower corners of runner 4. The ends of edge stripslfl are inclined as shown in Figure 4 and 5 to provide for bonding of the plastic bottom coating 6 to the wood runner 4 between the ends of strips 10 when they are placed endto end to form a complete edge for ski 2. Edge strips 10 may be further provided with recesses 30 as indicated in Figure 5, or holes 31 as indicated in Figue 6 to allow more area for bonding the bottom coating 6 to the wood runner 4 in the vicinity ofthe'metal edge strips 8.

v The bottom coating6 'of the runner 2 is bonded'to boththe woodenrunner 4 and the metal edge strips 10. Ihe lower surface 32of the bottom coating 6 is level and forms the bottom or sliding surface of ski 2. The upper surface 34 of the bottom coating 6 follows the contour ofthe lower surface of runner 2 with edge strips 10 attached thereto. Asshown in Figure 1, the bottom coatin'g'6 has relatively thick edges capable of being firmly fixed in place. It should also be notedthat the edge strips 10 have no coating thereon at the extreme lower corners of the ski .2.

T'Ihematerials' from which the members. of ski 2 are formed are conventional. The runner 4 may be made of wood, either solid or laminated as desired. The edge edge strips attached to said inclined surfaces between said runner and said covering material said edge strips extending to the sides of said runner, the outside edge portion of said edge strips being turned down along a longitudinal fold line to form an obtuse angle with thesides of said runner, the extreme outer edge'of the edge strips forming an acute angle with the lowermost face of the outside edge portion of the edge strips, whereby .sideways slipping of said ski in use is restricted, the lowermost surface of the outside edge portion of the edge strips together with the covering material forming the running surface of the ski. l

2. A ski comprising a runner substantially rectangular in cross section having substantially vertical sides and also having the lower surface thereof inclined upward for a short distance from. the sides toward the middle of said runner,"a coveringmaterialbonded to the lower surface of said runner, and elongated edge strips attached to said inclined surfaces between said runner and said covering material, said edge strips extending to the sides of said runner, the outside edge portion of said edge strips being turned down along'a longitudinal fold line to. form an angle of approximately 167% degrees with the vertical sides of said runner, the'extreme outer edge of the edge strips forming an angle offapproximately 77% degrees with the lowermost'face of the outside edge portion of the edge strips, whereby sideways slipping of said ski in use is restricted, the lowermost surface of the outside edge portion of the. edge strips together with the covering material forming'the running surface of the ski.

3. A ski, comprising a runner substantially rectangular in cross section having substantially vertical sides and also having the lower'surface thereof inclined upward for a short distance fromthe sides toward the middle of said runner, a covering material bonded to the lower surface of said runner, and elongated edge strips attached to said inclined surfaces between said runner and said covering material, said edge strips extending to the sides of said runner, the outside edge portion of said edge strips being turned down along a longitudinal fold line to'form an :angle of approximately 167% degrees with the vertical strips 8 may be made of spring steel. Polyester plastics or epoxy resins with magnesium filler may be used as a bottom coating for ski,2. The materials indicated are only illustrative of the invention and itv is not intended to restrict the invention thereto.

In use ski 2 with, edge strips 10 attached thereto will bepr'evented from slippingsideways to a'great extent by the metal edge strips 10. Because of the angle 18 of the surface 27 between the outside of the bent down portion of edge strips 10 and the sides of runner 4, the

ski 2 will tend todig into the surface on which it is skid Y ding thereby halting sideways slipping. Also, due to the particular angle 14 at which-the edge strips 10 are set in ski2; when the ski 2 is flexed in use the strips 10 tend to force the plastic coating 6 toward the center of the ski where the plastic coating is thick andwell bonded to wood runner 4 instead of tending to force the plastic coating'away from the runner 4 in the area of the edge stripsashas-beenthe case with past metal edgelstrips The drawing and the foregoing specification constitute a'description of the improved fabricated ski'in such full;
